Include the following improvements:

  1. Increase RPC retry latency to reduce server load that is caused by resent IO requests.

  2. Use current ULT to send DTX RPC instead of via dss_chore to avoid being blocked by some slow dss_chore uers.

Steps for the author:

  • Commit message follows the guidelines.
  • Appropriate Features or Test-tag pragmas were used.
  • Appropriate Functional Test Stages were run.
  • At least two positive code reviews including at least one code owner from each category referenced in the PR.
  • Testing is complete. If necessary, forced-landing label added and a reason added in a comment.

After all prior steps are complete:

  • Gatekeeper requested (daos-gatekeeper added as a reviewer).
